FILM-PACK.

Specication of Letters Patent.

Patented A-ug.l 6, 1907.

Application tiled January 28, 1905. Serial No. 243,056.

To all whm it may concern.'

Be it known that I, GEORGE LEWrs HOLMES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Film- Packs, of which the following is a specification.

My invention relates to photographic film packs and has for its object to provide new and improved constructions for devices of that class.

The invohtionis illustrated in the accompanying drawings wherein I Figure l is a perspective view of the pack with the front paper slip partially withdrawn. Fig. 2 is a longitudinal section through the pack. Fig. 3, a diagrammatic view showing in exaggerated longitudinal section a portion of the films and slips; Fig. 4, a longitudinal section through one of the films and tabs spread out flat and exaggerated in thickness; Fig. 5, a like v'iew of a modification; Fig.,l 6, a plan view of one of the films with its accompanying tab; Fig. 7, a similar view of one of the paper slips, and Fig. 8, a perspective view of the film packf'holdel or adapter.

Like letters of reference indicate like pd drawings. J

The pack consists o f a c ixse A, whichrnay beurnade of paper, card-board, or iother material, and, is, of course, to be constructed light proof. l e f ront side of this case is formed oflthe me A1 thmugh the aperture of which the filrris are Exposed. The upper side A2 of the casing has :n.aperture or slot through which the ends of the tabsIv and slips project. The material of the casing is preferably turned inward at this place as shown at A3 A* soas to make a li'ghtlock. Within the casing is a floating partition B about which' are folded and Adrawn the films and paper slips. This may be of card board or other material, and is shown somewhat exaggerated inv thickness in the drawings or the purposev of better illustration. vI `have Ashown one of these paper slips attened out in Fig.

7, designating it by the letter C. These-slips are vpreferably-made of. black paper orthe like inthe form shown, that is, witha rectangular part C1 and a be made of paper which can be colored soas to dis` tinguish them from the tabs-of the paper slips. A'

modification of this arrangement is shown in Fig. 5 where the tab Dl extends to ull length back of the 'The arrangement and operation of` thevfilms and the slips is best shownin the diagrammatic view of 3. As is shown, they are folded around the parrts in all the purpose. Likewise, the slip C and the tabs tition B in alternate order, a paper slip being on the outside of the completed pack. The ends of the slips and also of the tabs attached to the films extend back of the partition B and through the slot in the casing so as to be easily manipulated by the hand.

In order to hold'the .alternate films and paper slips close together and the front slip or film close against the frame work A1, I provide within the casing A a back plate E having the flat spring E which presses again stthe back of the casing. The slips and the tabs on the films, it will be understood, are successively drawn out through the slot in the casing, thus drawing the rectangular square ends oi the paper slips and the films respectively to the back of the pack behind the partition B. The ends of the tabs and slips it is found convenient to tear off as they are drawn out,

and for this purpose Ihave provided the metal cutting strip F which is secured to the partition B by the cross pieces F1, the latterbeing shown dotted lines in Fig. 2. These cross pieces serve as stops a inst which the shoulders of the tabs and slips abut.

In using the film pack of my invention it is not essential to have a holder or adapter. The casing oi the pack may be constructed so as to itinto the camera in the place of the usual plate holder, the iront paper slip protecting the first film from exposure. However, it may be convenient in some linstances to use thepack in connection with the holder or adapter, and I have shown such a device in Fig. 8'. It consists of a frame work G hinged at Gl to a back -part G2, the latter being provided with the iat spring G3 adapted to hold the film pack in4 position. '1 he ira-me may be secured to the back part by the hooks Gr4 G4 and the staples G5 G5 or in any desired manner. The upper member oi the irame work G is cut away as shown at G so as to orm n slot through which the paper tabs extend.

The casing A, I prefer to make of card board or the like, but any other material would answer' the same be of other material than paper. I,

The use and operation of my invention are as follows:

When tlrefilnr'pack 'comes to the user, the first lm is covered by'the outer paper slip, all oi the'slips and films bein/g vpressed against the frame work Al so as 'to prevent tne possibility of light leaking in. The film pack may be used with the ordinary plate camera and' D1 mightV in a manner similar to the use of plates, that is, the op- Verator may viirstiocus his lens with the aid of a groundV glass plate i-he chooses. He then inserts the film pack in the place in the camera usually occupied-by the plate holder, and taking hold of the paper tab at the back of the bunch of tabs, he pulls it out as far as it will go and tears it off on the cutter F. lThis uncovers the first film, vthe film below being protected by the next paper slip., When the exposure has been made, he takes hold of the next-paper tab,- this one being connected with the justexposed, and by drawing it out, pulls the film to the back of the pack.V

If he Wishes to make two exposures, when the first film has been exposed, he may take hold of two paper tabs at once and thus draw back simultaneously the front attached to the films, they may be easily distinguished fromy the ends of the black paper slips.

T he operation of the pack will not' be in any manner changed if it is used in connection with a holder or adapter. The pack is merely inserted into the adapter and the adapter used as above described. It Will be seen that in my device it is not necessary that the adapter should be light proof or have a shutter with its accompanying light lock, no1' indeed, is it essential that the adapter should be used at all. This is a very great advantage insornuch as the expense of a light .proof adapter With its shutter and light lock is very considerable.

It will be obvious that the pack may be removed from the camera at4 any time between exposures and in the day light as each film is protected by the ,paper slip in front of'it. i

y I claim:

1. A photographic film pack comprising a plurality/of films adaptedto' be successively exposed with a plurality of independent coverings arranged in alternate order therewith.

2. A photographic film pack comprising a plurality' of films with a pluralityp'of slips of light proof material arranged` inalternate order therewith in combination with means for successively and independently exposing such lilms and slips. v
